BIOLOGICAL CONTROL OF EARLY BLIGHT OF TOMATO BY THE GROWTH PROMOTING PSELTDOMONAS GLADIOLI B-25 STRAIN: EVALUATION OF DIFFERENT DELIVERY METHODSD. R. JAGADISH AND K.S. JAGADEESHAbstract An attempt was made to find out the effective delivery system of Pseudomonas gladioli strain B-25 for the control of early blight of tomato caused by Alternaria solani in pot cultures. Amongst different methods of application, combination of all five methods (seed treatment + soil application + nursery bed treatment + foliar spraying + root dipping) was found as the most efficient method. This method increased all the growth parameters and fruit yields of tomato substantially. The combined treatment method was the best treatment in controlling the disease to the maximum extent (60.2%) which was comparable to that of - the chemical control method (62.5%). The spectacular performance of the combined method was due to better survival and establishment of the bioagent in the rhizosphere.
